The 'Niteguard' is automatic. As soon as it becomes
dark a built-in infra red detector becomes operative.

It scans the surrounding area up to a distance of up
to 15 or 40 metres (depending on detector used).

When the heat of a human body is picked up by the detector it switches
on the 'niteguard' unit, to light a porch, garage entrance or whatever.
The days of fumbling in the dark for keys becomes a thing of the past.

The WIRELESS option external PIR's enable you to site
detectors in places (at the entrance to a drive, facing the
front door, near out buildings etc.) previously ruled
out because wiring was either impractical or expensive.

'Niteguard' is the most comprehensive system on the market today.
